I understand that osmo will turn off its fan during recording to allow for sound recording. However, with the fan turn on, osmo will overheat and shutdown in about 6-7 minutes. Is there an option to leave the fan on and allow for external recording instead. My objective is to make an hour of video recording.

In the sound option you can turn on / off your Fan option.

Hi, DTK. Please follow the advice in 2#. You can turn off the fan and the audio in camera setting of DJI GO app. Then osmo will use the audio of the mobile in the video.
